User manual ICOM IC-4008A

[. . . ] NEVER operate the transceiver with a headset or other audio accessories at high volume levels. AVOID using or placing the transceiver in direct sunlight or in areas with temperatures below 0°C or above +55°C DO NOT push the PTT when not actually desiring to transmit. i DO NOT modify the transceiver for any reason. DO NOT transmit for more than 3 sec. , when operating with the group mode and/or call ring function. Transmission in a form other than speech is limited, and should be of a duration of less than 3 sec. [. . . ] · Further adjustment of [VOL] may be necessary at this point. e Push and hold [PTT] to transmit then speak into the microphone. · Do not hold the transceiver too close to your mouth or speak too loudly. · The transmit indicator " " appears in the display. r Release [PTT] to return to receive. Time-Out Timer (TOT) The transceiver has a time-out timer function. This function prevents continuous, extended transmissions. This timer turns the transmission OFF 3 min. before the limit is reached, and the time-out timer turns OFF the transmission automatically. Another beep sounds to announce the end of the transmission. 10 RECEIVE AND TRANSMIT 5 Talk Range The IC-40Jr is designed to maximize performance and improve transmission range in the field. However, the single most important factor in transmit range is your surrounding environment. These radios are "line of sight" radios and as such, transmission range is influenced by the degree to which you can "see" the other communicating party. 192. 8 203. 5 210. 7 218. 1 225. 7 233. 6 241. 8 250. 3 OFF (unit: Hz) 15 9 RING FUNCTION ` Smart-Ring The Smart-Ring function has an answer back feature. This allows you to confirm whether or not a call has reached the receiving party. q Set the same group code number for all of your group transceivers. · A beep is emitted and " " flashes in the display. · When a member of your group answers your call, the transceiver emits beep tones for 10 sec. · When no answer comes back, the transceiver emits short faint beep tones. r Push [PTT] to answer and to stop the beeps and flashing. NOTE: This function is available only when the called station has set the same group number and the same operating channels as you. ` Call-Ring Sends the ring tones during transmit mode. ¯ While pushing [PTT], push [DOWN/Z] to send a ring tone. · The ring tone is emitted while pushing [DOWN/Z]. · The microphone signal is automatically cut while pushing [DOWN/Z]. 16 OTHER FUNCTIONS ` Initial set mode 10 Initial set mode is accessed at power ON and allows you to set seldom changed settings.
